One has to ask that if this aircraft was made by Airbus would the FAA have already grounded it?

They didn't ground the A330 after AF477 went down, did they?

Only one went down and the cause was not known for a long time.

Airline pilots on at least two U.S. flights have reported that an automated system seemed to cause their Boeing 737 Max planes to tilt down suddenly.

Singapore Banned 737 MAX Family

Singapore's civil aviation authority banned the Boeing 737 MAX family from its airspace.

According to the CAAS, five companies should be impacted by the ban: SilkAir, the regional subsidiary of Singapore Airlines, China Southern Airlines, Garuda Indonesia, Shandong Airlines and Thai Lion Air. All five operate Boeing 737 MAX aircraft in and out of Singapore.

Hamble_man. “Correct me if I wrong max speed flap 5 is 180kts”
Sorry Hamble_man but the max speed for flap 5 on the -800NG is 250kias and I believe it is the same on the max

Thank you maggot738. Speeds have changed a lot since I was on the 727 in the 80's. 250kts seems to be very excessive

China has grounden MAX8, but not MAX9.

EASA has grounded MAX8 and MAX9.

Nobody is talking about MAX7 - why?

Possibly because very few MAX7s have been produced, and the vast majority those have been to airlines in the USA and Canada: https://en.wikipedia.org/wiki/List_o...es_by_customer

Despite what Wikipedia claims, no Max 7 aircraft have yet been delivered.

Found this on another forum and I don’t know how accurate the info is...

You do realize the MAX8 was to be given a different type rating but MCAS was the solution to allow Boeing and the carriers to get around that so no new type rating was required for their pilots. Only a couple hours training on the new systems.

The MAX8 flew significantly enough different it was going to be a different type until MCAS was added to make it behave the same. This saved a ton of training and certification costs.

The problem is when in a problem situation and MCAS is disabled the pilots are for all intents and purposes now flying a type they have not been trained on.

If you don't believe me just open your eyes... Many many many pilots are reporting these issues. The FAA anonymous reporting system is full of such complaints.

This was a boondoggle from Boeings and the FAA's side.

.......>>> is one example.

Rather important is that it was in fact considered to have substantially different enough behavior to warrant a required type rating for pilots, obviated due to the software abstraction provided by MCAS. However, this abstraction is effectively disabled when setting stabilizer trim to cutoff which is one of the later steps in the normal troubleshooting sequence. OK? So the airplane is in an emergency situation, with a flight characteristic normalizing software routine disabled, thereby making it possible for the airplane to exhibit the very behavior that pilots were never informed of, never trained for, and not required to have a type rating for, that MCAS existed for in the first place.
I think that's quite a lot more relevant than airline safety records. Ethiopian Airlines has a good recent safety record anyway. And the outcry, upon MCAS being publicly revealed, among the U.S. pilot community I also think demonstrates important relative concern.
And, quite a concerning story about U.S. 737 MAX pilots using the anonymous aviation safety reporting system to communicate their concerns, whether instead of or because of the normal channels for doing so.

It didn't save on certification costs, because the 737 Max could not have been certificated as a new type.

Grandfathering it on the existing 737 TC was the only option that Boeing had, short of designing a completely new aircraft.

Speaking of news related to this thread, the US Transportation Secretary, Elaine Chao, decided to "lead by example" (or something like that) and fly on an AA 737 Max.
https://www.cnbc.com/2019/03/13/us-t...737-max-8.html
Elaine Chao and her staff flew on a Southwest Airlines 737 Max 8 from Austin, Texas to Washington, D.C. hours after the Transportation Secretary was emphatic in saying her department will ground Max planes if it’s determined they are not safe to fly.
I heard of this on the radio about an hour ago. Both American and Southwest are content to keep flying the MAX (for the time being). I will guess that they have provided some form of formal reasoning to the FAA et al ... I'd be interested to see what was in those memos.

Canadian Minister of Transport's statement:

Minister Garneau statement regarding restricting airspace to Boeing 737 MAX 8 and 9 aircraft

No sign of the Safety Notice itself on the TC website yet.
